WILLIAM H. FULCEER, or oAxLAnD, 'camromrm.
Roma's PULVERIZER.
Applicationflled November 14, 1921.- Serial No. 515,128.
State of California, have invented new and useful Improvements in Rotary Pulverizers,
of which the following is a specification.
The present invention relates to improvements in grinding mills, the object of the invention being to provide a grinding mill into which the material to be ground can be fed intermittently and ground continuously and very effectively, and discharged in a pulverized condition.
2.5 In the accompanying drawings, Figure 1 is a broken side view of my improved grinding mill, Figure 2 is a vertical section of the hopper; Figure 3 is a horizontal section on the line 33 of Figure 1; Figure 4 is a top plan view of a stationary cone detached.
Referring to the drawing, 1 indicates a concrete foundation, on which is supportedan annular base 2, which supports a conical 26 body 3 secured by bolts 4 to the concrete foundation, said body comprising two sections bolted together, as shown at 6, and
carrying keys 7, by which are secured upon said body remova le mantles 8, forming a conical surface. Around said conical body is a conical shell 9 madein sections secured together, as shown at 11, and lined on the inside by concaves 12. The lower portion of the shell is formed with an inwardly andv 85 downwardly extending flange 10 which en gages the lower edges of the concaves and supports the concaves 'when notresting on the mantles. Said shell is. formed with a flange 13, to which is secured a gear ring 14, driven by a pinion 16 on a vertical shaft 17- having bearings in a standard 18, and having secured thereto a bevel wheel '19 meshing with a bevel wheel 21 on a horizontal shaft 22in bearings 23, and carrying a pulley 24, 1
by which any suitable. power may be employed torotate the shaft. Also said shell is formed at its base with a flange 26, which rotates in contact with rollers 27 supported by suitable mountings 28. Said shell is 5 formed at the top with a flange 29, which is secured by bolts 31 to a flange 32 of a conical head 33, also made up of' sections bolted together, and in the upper open end of said head is contained a hopper 34'. A-base 36 is w secured by screws 37 toan inwardly extendannular space 41.
From the under sideof the flange 26 depends lugs 42, which, at the advancing ends,
.have upwardly extending lower surfaces so as to taper to the front. The lower surfaces of the rear halves of the lugs are horizontal. The front ends of these lugs are adapted, in the rotation of the shell, to engage and ride. upon rollers 43, having shafts connected by a mug 46 having extensions or loops 47, said rollers rolling on a circular track 48. As the shell rotates these lugs impinge upon the rollers and roll thereover, at the same time, because of the upwardly sloping lower surfaces of the'lugs, causing the shell to be slightly raised, and permitting the material between the mantles and the concaves to drop slightly therebetween until the lugs roll off said rollers, whereupon the shell and concaves drop suddenly upon the material.
next series of lugs, which thereupon ride on i said rollers, and the process of raising the shell and subsequent descent and crushing of the material is repeated. q
vIt is to be observed that, as the ring'46 rotates, the rollers 43 mounted thereon contact with the lugs 42 always at vdifi'erent points of the track 48, so that there is uniform wear aroundthe track and also in the shell, because'the shell drops at a different place each time. 1 I
The head 33 of the cone is hollowed out, so that when the shell is raised and suddenly dropped again due to the action of the lugs 42 on the rollers 43, said hollowed out portion serves as a pump to strongly force the water and material to be crushed'into the The crushed material falls into inclined circular trough t9 surrounding the lower edges of the mantles, and said inner surfaces of the lower portions of the concaves.
I claim L-The combination of a conical. body, a conical shell surrounding said body, means for feeding material into the space between said shell and body, means for rotating said shell, elements depending from said shell, and arranged to move in a circular path 'as the shell rotates, rollers rollingin a circular path immediately beneath that of said elements, and adapted to be engaged by said elements to elevate said shell, and means for connecting said rollers whereby they roll at constant distances apart. v
2; The combination of a conical body, mantlessecured thereon, a conical shell'surrounding said body, concaves secured insald shell, means for feeding material into the space between said concaves and mantles,
means for rotating said shell, elements de pending from said shell, and arranged-to move in a circular path as the shell rotates,
rolling constant distances apart.
mantles secured thereon, a conical shell surrounding said body, concaves secured in said shell, means for feeding material into the space betweenv said concaves and mantles, means for rotating said shell, lugs depending from said shell, and having lower surfaces the front portion of" each of.which slopes upwardly forwards, said lugs being arereby they, roll at constant dis-- ranged to move in a circularpath as the shell rotates, rollers rollin in aclrcular path immediately beneath t at of the lugs, and
means for connecting said rollers, whereby they rollat constant distances apart.
t The combination of a conical body, mantles secured thereon,.a conical shell surrounding said body, concaves secured in said shell, having depending cylindrical lower portions fitting c means for feeding material into the space beosely around the'mantles, v
tween said concaves and mantles, means for rotating said shell, lugs depending from said shell, and havmglower surfaces the front ortion of each of which slopes upwardly orwards, said lugs being arranged to move in a circular path as the shell rotates, rollers v in a'circular path immediately beneath that of the lugs, andmeansIfor connecting said rollers, whereby they roll at WILLIAM H. l ULOHER.
